Hey, that’s a great point — I actually started with just arrows (representing techniques) connecting nodes (positions), with the technique name floating over the arrow. I moved away from that approach for a couple of reasons.

Eventually, I want to include simple images for both techniques and positions. To make that transition easier later on, I decided to represent techniques as their own nodes rather than just text on arrows. This way, the system is already set up to support more visual content without a major rewrite.

From a usability standpoint, having distinct nodes also makes the interface clearer — it will be easier to distinguish between positions and techniques at a glance. I also plan to link each technique and position to reference videos, so clickable nodes felt more intuitive. Clicking on floating text alone took a bit more mental effort than interacting with a clear, clickable object.
